PURPOSE:To spark-discharge high voltage generated by generating attracting force between a stator and a movable piezoelectric body and increasing impact force by gas pressure to a conductor of the movable piezoelectric body. CONSTITUTION:When a movable piezoelectric body 44 is crashed to the conductor 67 by gas pressure, impact force is applied to the piezoelectric element 55 and high voltage is generated, and spark discharge is generated between the most end 81 of an electrode 79 for discharge electrically connected to one electrode of the piezoelectric element 55 through a collision terminal 58 and the conductor 67 and the most nose 84 of an electrode 83 for discharge electrically connected to the other electrode of the piezoelectric element 55 through a terminal body 63, a main body 45 and a cylinder body 30. Gasoline and an inflammable gas and the like are ignited by the sparks. |
